Of course, getting children to randomly write some numbers on bits of paper has no Supporting evidence!

Supporting Evidence is the critical aspect, and I have it!

See the Image's Below:

1/R_T = 1/R1 + 1/R2 = 1/70 + 1/70 = 1/0.02857142857142857142857142857143 = 35.00 and power is V² / R = P = 25V² / 35.00 = 17.85714 Watts
1/R_T = 1/R1 + 1/R2 + 1/R3 = 1/70 + 1/70 + 1/19.2 = 1/0.08065476190476190476190476190476 = 12.40 and power is V² / R = P = 25V² / 12.4 = 50.40323 Watts

Gyula's handy guess work is not valid and I have just proven it! Oh dearie me, How Sad, Never Mind!

You're going to have to sharpen your pencils!

I always measure my circuits with


current probe + voltage probe + scope math


and never had any problems.




Why to use precision resistors when there is so much which can go wrong
while using them?


Is there any special reason?

We measure Excess Power!

Well, there's your problem...

EMJunkie,  you already acknowledged Partzman's comments on the issues of Rigol scope measurements (8 bit vertical resolution
and the need for arranging the displayed waveforms to the fully available vertical display etc), remember? 
Now you show the same scope shot again, on which nothing was fullfilled from the requirements you did agree with. 
Your "supporting evidence" is garbage in garbage out.

Of course, getting children to randomly write some numbers on bits of paper has no Supporting evidence!

You have been doing this on the keyboard, no?  Your posts clearly prove that. 

Why do not you check the MR16 LED lamp for its power consumption like the two videos show, it would be a few minutes long test. 

Your own test results would reveal first of all for yourself how ridiculous your claim of the 30 W
for that LED bulb  was.  LOL 

BUT wait! the 30 W was your guess work !
Oh dearie me, How Sad, Never Mind!
